Modern smartphones of the line Xiaomi, running on the shell MIUI or new HyperOS, offer users advanced capabilities for working with peripherals. Wireless connection has become the de facto standard, allowing you to enjoy music and conversations without unnecessary wires. However, the initial setup process sometimes raises questions for those who are switching to the ecosystem for the first time Android or changing the headset model.
Proper synchronization of devices requires an understanding of how the data transfer protocol works and what hidden settings can affect the sound quality. In this article, we will analyze in detail the algorithm of actions for successful pairing, consider the nuances of working with different models of accessories and give recommendations for optimizing energy consumption.
Regardless of whether you use branded Redmi Buds or third-party headsets from Sony or JBL, basic the connection principle remains the same for all devices running this operating system. The main thing is to follow the sequence of actions and know where to look for the necessary switches in the settings menu.
Preparing devices for pairing
Before starting the procedure, you must make sure that both devices are ready for interaction. Charge your headphones and smartphone to a level of at least 20-30% so that during the setup process there is no sudden power cut. This is critical, as interrupting the encryption key exchange process may cause the module to malfunction.
Activate discovery mode on your headset. In most cases, to do this, you need to hold down the power button or a special pairing button for 5-7 seconds until the indicator starts blinking blue or white-blue. It is the rapid blinking of the indicator that signals that the device is visible to others gadgets. If you have a case with touch controls, sometimes you need to take out the headphones and press the touch zones at the same time.
On your smartphone Xiaomi make sure that the function Bluetooth is turned on. For quick access, swipe down from the top edge of the screen to open the notification panel and tap the corresponding icon. If the icon is gray, click on it to turn it blue. Also check if airplane mode is activated, which blocks all wireless interfaces.
⚠️ Attention: Some headphone models automatically exit pairing mode after 2-3 minutes of inactivity. If the phone does not find the device immediately, repeat the procedure for activating the search mode on the headset.

After successful connection, it is important to configure the device’s operating profile to suit your tasks. In the Bluetooth menu, by clicking on the gear icon or arrow next to the name of the connected headphones, you will be taken to the advanced settings of a specific device.
Here you can activate the function High quality audioif your headphones support codecs LDAC, aptX or aptX HD. This allows audio to be transmitted with less compression and a higher bitrate, which significantly improves the detail of the tracks. However, it is worth remembering that this may increase battery consumption.
Also in this menu there is an option to split the sound into two devices. If you have second wireless headphones, you can stream music to both pairs simultaneously. This is convenient for sharing listening on trips or when watching movies with a friend.
| Parameter | Description | Impact on operation |
|---|---|---|
| AAC codec | Standard compression format | Balance of quality and power consumption |
| LDAC codec | High resolution audio | Better sound quality, higher battery consumption |
| Call duplication | Sound in the phone and headphones | Convenient for conferences, but the phone sits down faster |
| Voice assistant | Activation by button | Quick access to functions phone |
The choice of the correct codec depends not only on the headphones, but also on the processor model of your smartphone. Xiaomi flagships usually support a full range of modern codecs.
Solving problems with detection and connection
Sometimes users are faced with a situation where the phone does not see the headphones or the connection is constantly disconnected. First of all, try to “forget” the device. To do this, go to the Bluetooth settings, click on the name of the problematic headset and select Cancel pairing or Delete.
After removal, reboot your smartphone. This will clear the network services cache and reset possible software errors in the operation of the communication module. Then repeat the search procedure from the very beginning, making sure that the headphones are in pairing mode.
